Definitions

  • the invention relates to a device for pressing control of a transmission means a continuously variable transmission, according to the preamble of claim 1.
  • Such continuously variable transmissions are, for example, toroidal or Traction mechanism, wherein the contact pressure of the transmission means - for example a link chain or a push belt - mostly is controlled torque-dependent. This should on the one hand a largely slip-free transmission of the drive torque allows, on the other hand However, efficiency losses and wear due to excessive pressing the transmission means are counteracted.
  • the object of the invention is to provide a device for Anpress horrung a Show transmission means of a continuously variable transmission, the easier and robust construction, a continuous adjustment of the contact pressure realized both torque and translation dependent.
  • the Anpress felung can directly, so directly on the lever and the rolling elements, or indirectly by throttle control of a superimposed be accomplished hydraulic pressure.
  • Fig. 1 is a detail of a continuously variable belt transmission 10th Unless described, known type shown; in so far, for example refer to the Fig. 1 DE 195 45 492 A1.
  • the belt transmission 10 has a drive disk pair in a known manner 12 on that with a drive shaft 14 rotatably in a not shown Gear housing is mounted and that via a link chain 16 a driven pulley pair (not shown) drives.
  • the pair of drive disks 12 (and of course also the output disk pair) has a fixed disk 18 and one via a toothing 19th non-rotatable, but axially displaceable path plate 20 on; by hydraulic Adjustment of the spacer disk 20 relative to the fixed disk 18, the Link chain 16 within the two drawn end positions for adjustment a desired transmission ratio changed continuously become. This is done by pressurized hydraulic fluid from a not shown hydraulic control via the channel 22 in the drive shaft 14 of a first hydraulic chamber 24 supplied or from this dissipated.
  • the spacer disk 20 rotatably carries a drive bell 26, which via radial inwardly projecting driver 28 axially aligned sliding guides 30th pierced in rectilinear levers 32 (see also Fig. 2).
  • the drivers 28 engage in longitudinal grooves 34 of an annular control sleeve 36 a, which is guided on the shaft 14 with a hub portion 38, wherein the annular edge 38a a throttle in conjunction with a discharge channel 40 forms for hydraulic fluid.
  • each over Bolt 50 hinged to a drive gear 52 of the belt drive 10 are connected.
  • the other drive-side gear elements with a gear 54 on another gear shaft are not shown.
  • the drive gear 52 is connected via a roller bearing 56 on the transmission shaft 14th rotatably mounted.
  • the levers 32 each carry between the support point on the drivers 28 and the bolt connection 50 a roller 58, which on a bolt 60 of the Lever 32 is rotatably mounted and cooperates with a respective ramp 62, wherein the ramps 62 are formed in the control sleeve 36. It is still too mention that the driver 28 on the drive bell 26 backlash in the Sliding guide 30 are guided and the longitudinal grooves 34, the control sleeve 36 rotationally secure.
  • the Anpress chargedung the link chain 16 via the spacer plate 20 is like follows:
  • FIGS. 3 and 4 show a further embodiment, which is to avoid of repetitions is described as far as it is essential from the embodiment according to FIGS. 1 and 2 deviates. Same parts are with provided the same reference numerals.
  • the three levers 70 are cross-shaped, wherein in each case one arm 72 by means of a bolt 74 on the drive gear 52 'is hinged, the oppositely projecting arm 76 in a bag-shaped Recesses 78 of the annular intermediate wall 42 'engages and the two transverse arms 80,82 interact with rolling elements or balls 84,86.
  • the balls 84,86 of the three levers 70 are in adjacent, annular Ball cages 88,90 out, the ball cages 88,90 radially projecting Mit loved 92.94, in obliquely oriented guide slots 96,98 of an annular extension 100 on the drive bell 26 ' protrude.
  • the guide slots 96,98 per lever 70 are converged as shown in FIG. 5, so that upon displacement of the spacer plate 20 with the drive bell 26 and 26 ', the ball cages 88,90 on the driver 92,94 rotated against each other or the balls 84,86 as in Fig. 3 based on the Spheres 84 are shown, moved towards or away from each other and thus form the variable lever length b.
  • the fixed lever length a results from the distance between the Bolt connection 74 of the arms 72 and the point of application of the arms 76 at the pocket-shaped recesses 78 of the intermediate wall 42 '.
  • the balls 84, 86 in turn act on a radial, annular contact surface 102 on the control sleeve 36 '.
